Iscar 6004450 Cutoff Insert IC830 Carbide 3mm Tang-grip

Product Description

The ISCAR 6004450 is a solid carbide cutoff and parting insert carrying the TAGR3JS15D designation and IC830 manufacturer grade. Engineered for the Tang-Grip clamping system, this single-end insert features a 3.00 mm (0.1180 inch) cutting width and a 15-degree right-hand lead angle. The PVD-applied IC830 coating is formulated for high-performance cutting in superalloy and difficult-to-machine materials. A JS chipbreaker geometry controls chip flow during deep grooving and parting operations. The 7-degree relief angle and 0.02 mm corner radius (0.0008 inch) deliver precise edge integrity on demanding workpiece materials. Licensed machinists and CNC operators install this insert on compatible Tang-Grip toolholders in production turning environments.

This insert is suited for parting and cutoff operations on CNC lathes and turning centers handling superalloy, steel, and stainless workpieces. The right-hand orientation positions it for standard front-tool-post and gang-tool configurations. The IC830 PVD grade performs reliably at elevated cutting temperatures common in aerospace, power generation, and precision machining applications. The JS chipbreaker promotes controlled chip evacuation in interrupted and continuous parting cuts. Sold individually; minimum order quantity is 10 units per order.

Key Features

• IC830 PVD-coated solid carbide grade optimized for superalloy and difficult-to-machine materials
• 3.00 mm (0.1180 inch) cutting width for consistent parting and grooving slot dimensions
• 15-degree right-hand lead angle reduces entry forces and deflection during parting
• JS chipbreaker geometry promotes reliable chip control in deep cutoff passes
• Tang-Grip clamp-held insert style for secure, repeatable seating in compatible toolholders
• Single-end design; 7-degree relief angle and 0.02 mm corner radius for edge precision

Compatibility

Designed for use in ISCAR Tang-Grip series toolholders that accept TAGR-style inserts with a size code 3 profile. Verify toolholder designation and insert pocket geometry before ordering.

Installation Notes

Insert replacement should be performed by a qualified machinist or CNC tooling technician with the machine fully stopped and in a safe, locked-out state. Use the appropriate Tang-Grip clamping tool or wrench as specified by the toolholder manufacturer — do not improvise clamping methods. Inspect the insert pocket and clamping screw for wear or debris before seating the new insert. Handle carbide inserts with care to avoid chipping the cutting edge prior to use.
